West Brom’s Allan Nyom was booked in the 33rd minute after a number of fouls on Zaha.
The wideman was also involved in clashes with Albion’s James Mcclean and Claudio Jacob.
De Boer added: “I saw some signs of wanting to bring the beauty of the game here and the beauty of the game is not those kinds of challenges.
“I think I have to give Wilf a good compliment because he stayed calm and spoke with his feet.”
Baggies boss Tony Pulis hit back: “I thought it was a very competitive game. I didn’t think there was any malice in Allan’s challenges.”
Midfielder Luka Milivojevic opened the scoring for Palace – who won 2-0 – with a superb free-kick from 25 yards, after Craig Dawson brought down Zaha.
Bakary Sako added a second, when his shot from outside the box deflected off Dawson and Ahmed Hegazy to wrongfoot keeper Ben Foster.
Zaha later put a message on Instagram, claiming fans of his former club Manchester United and rivals Liverpool had posted racial abuse on his timeline.
